VENTILATED GLASS-SETTING FOR WINDOWS.

Application filed Apr1l9, 1909, Serial No. 488,962.

To all whom it may concern:

Be it known thatI, GEORGE G. Hns'rnn, of Portland, in the county of Multnomah, and in the State of Oregon, have invented a certain new and useful Improvement in Ventilated Glass-Settings for Windows; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of a portion of a display window embodying my invention, viewed from the outside;

Fig. 2 is a perspective view of aportion of one of the side bars;

Fig. 3 a perspective view of the corner bar; and

Fig. 4: a detail view in perspective of one of the corner bar clamps.

My invention relates to window construction suited more especially for display or store fronts, in which the sheets or panes of glass are mounted in bars formed of sheet metal, and the objects of my invention, generally stated, are the efficient and satisfactory ventilation of the window, and the prevention of the collection of moisture or the sweating of the glass, and frosting thereof; the proper cushionin of the glass to revent its accidental crac ing or breaking; and the more convenient erection of the window parts, but without any sacrifice of appearances and strength, and for the accomplishment of the ends or objects that I have in view my invention consists in the window construction substantially as hereinafter specified and claimed.

In the embodiment of my invention illustrated in the drawings, I show a window having, as is common, two panes or sheets of glass 10 arranged at an angle to each other, a corner bar being provided at the angle or corner formed by the two panes of glass, and the side edges of the glass away from the corner bar being supported by vertical sash bars, and the bottom edges by horizontal sash bars, all secured to a framework 11. The vertical and horizontal sash bars are alike inconstruction. Each consists of two parts, one being a rail 12 of sheet metal that is in the form of. a right angle in cross section to engage corespondingly angled surfaces on the framework 11,

and the outer edge of said rail is bent inward at practically a right angle to form a r1b or flange 13 which engages one edge of the other member, which is in the form of a rail or bar 14: of sheet metal, that constitutes a glass clamping bar, its other edge belng bent to form a longitudinally extendlng groove 15 that receives a half round cushion strip 16 of wood or other suitable cushioning material, whose fiat surface has contact with the surface of the plate of glass. The portion of said rail between its two said edges are inclined away from the inner side of the rail 12, so that when securing screws 17 passing through openings 1n the clamping rail and through openings insaid rail 12 and into the framework 11, are tightened up, they will cause the clamping bar to yieldingly, but nevertheless securely, hold the glass, a sufiicient elasticity or spring. in the clamping bar being provided to prevent its action upon the plate of lass being too rigid. The cushioning or pac ring strip 16 will accommodate itself to the position of the glass by rocking in its bearings formed in the clamping bar, even though the angle of the clamping bar changes somewhat. The formation of the clamping bar 14 in cross sections, and its inclination with reference to the side of the rail 12 besides giving a sufficiently yielding nature to the clamp to prevent damage to the plate of glass, forms or provides a channel or space within the sash bar for the circulation of air, and to es tablish communication between the inside and outside of the window, the contiguous portions of the rail rib 13 and the edge of the clamping bar 14 are provided with alining notches that form small holes 18 that are located at suitable intervals along the sash bar to provide an adequate circulation of air. Besides the cushioning action of the clamping bar, the plate of glass is further cushioned by being placed at intervals in contact with cushions 19 of some soft or yielding metal, such as lead, that are in the form of short bars that are L-shaped in cross section and seated in the corner or angle of the rail 12, so that the edge and side surfaces of the glass have a bearing on said cushions. Besides constituting a yield ing support for the glass, the cushions 19,

since they are separated from each other, provide air spaces that complete the co1nmunication between the inside of the wlndow and the outside of the Window for purposes of ventilation. The edge of the cushion member that overlaps the inner surface of the glass is inclined laterally and inward toward the other member of the cushion, so as to avoid the collection of moisture or dust thereon, the angle of inclination being such as will conduce to the ready assage of matter falling on such edge. nstead of making a miter joint where the two clamping bars 13 adjoin each other at a corner, the ends of said bars at such point are cut off or left at a right angle, and the gap or space which thus exists at such corner 1s covered by an angle piece 20 that conforms to the outer surfaces of the bars and is held in place by the same clampin screws, and such angle piece in itself constltutes a clamp that adds strength to the structure and at the same time enhances its appearance.

For the corner bar, I employ a part-tubular rail 21 of sheet metal that engages the sheets or panes of glass at the corner or angle on the outside thereof, and has its glassengagin parts formed by inwardly bent ribs or anges 22, and at intervals there are substantially T-shaped clamping blocks 23, whose fingers or arms are curved to interlock with the inner sides of the glass-engaging ribs or flanges 22, said blocks having each a threaded opening for the reception of a screw 24 passing through a glass-em gaging bar or strip 25 that engages the two sheets or panes of glass on their inner surfaces, a stri of felt 26 or other cushioning material being preferably interposed between s'aid clamping bar or strip and the glass. In order to hold the clamping blocks 22in position for the application of the screws, and yet admit of their ready shifting along the bar or rail 21, to the desired position, I provide on each of said blocks a friction device consisting of a spring 27 fastened thereto and curved-or bowed in form, so that it may yieldingly engage the inner surface of the corner bar or rail 21. At the lower end, the bar or rail 21 rests upon a foot 28 that has a vertical bar-engaging member 29 within the same, and an outwardly extending horizontal flange 30 having a hole for a fastening screw 31. The outwardly extending flange 30 of the foot is important in that it enables the glass to be set from outside the window instead of from the inside. In order to cover said foot, and produce a good finish, I employ a quadrant or curvilinear covering piece or molding 32, that at each extremity overlaps the end of the horizontal sash bar contiguous to the corner bar, and is secured in place by screws 32. I

While I illustrate and have described my spaced invention as en'rbodied in one structure, it is to be understood that a structure may be made in which all the characteristics or features of my invention will not be einbodied, andmy claims are to be construed in the light of this statement.

Having thus described my invention, what I claim is- 1. A sash for glass settings comprising a rail of sheet metal that passes beneath the glass plate so as to extend inside and outside the same, said rail having inside the glass an integral up-standing rear flange spaced away from the inner side of the glass, means consisting of members reaching forward from said flange and constituting bearings for the glass on its inner side and above the lower edge of the glass, said members being spaced apart, means for supporting the glass spaced above the portion of said rail forward of said rear flange, providing communication beneath the glass with the spaces inside and outside the same, a bar situated between the outer side of the glass and the upper side of said rail forward of the plane of the outer side of the glass, and means for clamping said bar against the outer side of the glass.

2. A sash for glass settings comprising a 'rail of sheet metal that passes beneath the glass plate so as to extend inside and outside the same, said rail having inside the glass an integral, up-standing rear flange away from the inner side of the glass, means, consisting of yieldable material, separate from said flange and having bearin contact, at separated points, with said g ass, and in advance of said flange, means for supporting the glass spaced above the portion of the rail forward of said flange, a bar situated between the outer side of the glass and the upper side of said rail, and means for clamping said bar against the outer side of the lass.

3. A sash bar or windows comprising a bar or rail having at its edge a projection beyond the glass on one side thereof; a lass holding bar lying between said side 0 the glass and said projection, and having a glass-engaging member at one edge and a flange at the opposite edge to engage the projection of said rail on the inner side thereof, said glass-holding bar being in clined between its glass-engaging portion and its flange and perforated, and a support for the opposite side of the glass, spaces being between said support and the glass in gommunication with the space within said 4. The combination of a sash bar, a sheet of glass, and spaced cushioning blocks engaging the edge of the glass, having portions overlapping the side surface of the glass, the outer edge of said portions being inclined.
